For each condition-prefix pair, we randomly generated 10 sentences (each of 60 tokens) and picked out 3 reasonable sentences (without degeneration issue). We do this for every pair and for both our method and PPLM, ending up with 54 sentences.
Unlike in [1]} where A/B testing is conducted as part of its ablation study, we do not have enough time and resources to generate statistically significant text pairs.
